Why Dzhokhar Tsarnaev May Never Make It To The Death Chamber

Boston Marathon bomber Dzhokhar Tsarnaev is years from the death chamber -- if he ever makes it -- despite Friday's sentence by a federal jury.

A lengthy appeals process, as well as legal and technical complications with lethal injection, are just some of the factors that could prevent Tsarnaev, 21, from receiving the punishment the jury imposed:

Timothy McVeigh, convicted in 1997 of bombing a federal building in Oklahoma City, was on death row at the U.S. Penitentiary in Terre Haute, Indiana, for four years before abandoning his appeals, expediting his execution.

Tsarnaev's defense likely will file several post-trial motions, which may include objections to the fact the trial was held in Boston, denying him a truly impartial jury. Other motions could arise if information surfaces that jurors were untruthful on disclosure forms, or that there was impropriety during deliberations in the jury room, WBUR reports.

The Death Sentence Could Be Tossed Out Or Vacated

A judge overseeing Tsarnaev's appeal has the power to throw out or otherwise vacate the Boston jury's sentence based on new evidence or prosecutorial decisions made in the post-conviction phase. In one such example, confessed killer Gary Lee Sampson was handed the death penalty, only to have the sentence vacated when it was revealed that one of the jurors lied during the screening process, The Boston Globe reports.

As a result, the U.S. Bureau of Prisons doesn't have the drugs to carry out lethal injection.

“The Department of Justice has been conducting a review of the federal protocol used by the Bureau of Prisons, and has had a moratorium in place on federal executions in the meantime,” Patrick Rodenbush, a spokesman for the department, told The Washington Post in a statement.

If the Justice Department decides later to allow lethal injections, it will still face the same drug supply shortage that state departments of correction have been grappling with for the past several years.

As For The Victims...

Death penalty opponents have noted the long process that awaits not just Tsarnaev, but the hundreds of victims of the 2013 tragedy. In April, the parents of 8-year-old Martin Richard penned a passionate op-ed in the Globe pleading for the Justice Department to drop the death penalty against Tsarnaev. Richard was one of the four people killed in the bombing. His family argued that life without parole is the only way to close the book on the tragedy:

We understand all too well the heinousness and brutality of the crimes committed. We were there. We lived it. The defendant murdered our 8-year-old son, maimed our 7-year-old daughter, and stole part of our soul. We know that the government has its reasons for seeking the death penalty, but the continued pursuit of that punishment could bring years of appeals and prolong reliving the most painful day of our lives. We hope our two remaining children do not have to grow up with the lingering, painful reminder of what the defendant took from them, which years of appeals would undoubtedly bring.
